Wind-Resistant Irrigation Tower Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional irrigation systems are vulnerable to high winds, which can cause the irrigation towers and water pipes to tip over, leading to system damage and increased repair costs due to their high center of gravity and lack of wind resistance.
Innovation Solution
The system incorporates wind-resistant irrigation towers with adjustable vertical and horizontal members, equipped with actuators that can lower or raise the towers based on wind speed data from sensors, reducing the frontal area and center of gravity to prevent blow-over during high winds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the irrigation towers are positioned high to enable sprinkler operation, then irrigation function is improved, but wind resistance deteriorates causing blow-over damage
Solution Approach 1:
The irrigation tower employs movable vertical members that can dynamically adjust their height and position. The vertical members are configured to pivot at connections with horizontal members, allowing the tower to transition between elevated operational positions and lowered wind-resistant positions, resolving the contradiction between needing height for irrigation and needing low profile for wind resistance
Solution Approach 2:
The tower structure changes its geometric parameters by adjusting the vertical position of vertical members relative to horizontal members. This parameter adjustment allows the tower to modify its center of gravity and frontal area, enabling it to operate at high positions during calm conditions and lower its profile during high wind conditions, thus resolving the reliability-ease of operation contradiction
2Productivity
If the irrigation system operates continuously, then productivity is improved, but damage from high winds increases
Solution Approach 1:
The system uses wind sensors to detect high wind conditions before they cause damage, and the controller automatically lowers the vertical members in advance to a safe position. This preliminary action allows the irrigation system to continue operating during moderate winds while proactively protecting itself from severe wind damage, maintaining productivity while reducing wind-related harm
Solution Approach 2:
The irrigation system incorporates wind sensors that continuously monitor wind conditions and provide feedback to the controller. The controller processes this feedback and automatically adjusts the tower height by moving vertical members, creating a closed-loop control system that maintains productivity while responding to wind conditions in real-time, thus resolving the contradiction between continuous operation and wind damage prevention
3Reliability
If automated wind response control is implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The irrigation tower incorporates wind sensors and a controller that automatically detect wind conditions and adjust the vertical member positions without human intervention. This self-service capability allows the system to autonomously respond to wind threats, improving reliability while the modular design keeps the added complexity manageable through standardized sensor-controller-actuator integration
Data Source
AI summary
An irrigation tower is provided. The irrigation tower includes one or more of a pair of vertical members, a first end of each coupled to a water pipe and configured to pivot in relation to the water pipe, a horizontal member, each end coupled to a second end of each of the pair of vertical members and configured to pivot in relation to the second ends, and a plurality of wheels, each coupled to the horizontal member. A distance between ends of one of the horizontal member or the pair of vertical members is configured to change to lower or raise the water pipe with respect to the horizontal member.
